Abstract
Ocean Thermal Energy Conversion (OTEC) exploits the thermal disparity between chilly abyssal water and warm surface water to generate energy. The quantity of energy the Earth acquires from the sun within a single diurnal cycle is sufficient to satisfy the planet's energy requirements for an entire annum, with approximately 80% of that solar energy being assimilated by the ocean. The conversion methodologies concentrate on open, closed, and hybrid cycle facilities. Efficiency investigations underscore the significance of facility distance and thermal gradient, whereas economic assessments take into account per-unit expenditure and offshore distance, influencing power generation expenses. Illustrations are presented utilizing derived efficiency and economic formulations. While 1 MW OTEC facilities are presently operational, the manuscript underscores the necessity of establishing larger 10 MW facilities, which are viable yet untested, to enhance methodologies and facilitate broader implementation of OTEC technologies in the future.
